Oronteus Finaeus (1494-1555) was a celebrated cartographer who produced a map in 1531 which is claimed by some that, like the Piri Reis Map, it depicts the coast of an ice-free Antarctica. Charles Hapgood rediscovered it in 1959(a) in the Library of Congress. This idea is then used to support the concept of the existence of a very early civilisation that was capable of sophisticated map-making. It is then just a short step to name this civilisation ‘Atlantis’. Some, such as the Flem-Aths went further and actually nominated Antarctica as the home of Atlantis.
Robert Argod has used the Oronteus Finaeus Map to support his contention that the Polynesians had originated in Antarctica.
>Christine Pellech has an article published on the Atlantisforschung website taken from her 2013 book Die Entdeckung von Amerika  (The Discovery of America), in which she reviews the range of medieval maps displaying geographical details ‘unknown’ until centuries later!(e) Her reference to the Mark McMenamin coins can be ignored as they have since been shown to be forgeries (See: Sardinia).<
However, a contrary view has been expressed by Paul Heinrich who commenting on Graham Hancock’s assertion that the map shows an ice-free Antarctica, points out that in the case of West Antarctica, the underlying bedrock is, in the main, hundreds of feet below sea level and would not show on a real map of the region(c).
A more recent website(b), although not endorsing an Antarctic Atlantis, discusses some of these old maps in very great detail and on Graham Hancock’s website. The site is based on a number of chapters from a work-in-progress, The Atlantis Maps: The Rise of Atlantis and the Fall of a Paradigm by Doug Fisher. He identifies the Plain of Mesopotamia in Northern Argentina as the location of Atlantis.
